While you can turn the device on and off using the power key, the device will likely not be easily accessible to do so. You should consider connecting a switch or one of the following to turn the GPSMAP^® 9500 device on and off:

• A GRID™ device

  NOTE: A GRID 20 device will not turn the GPSMAP 9500 device on or off. Using the power key on the GRID 20 device will place the GPSMAP 9500 device into sleep mode.

• Another Garmin^® chartplotter

• A GMM™ monitor

When power is applied to the GPSMAP 9500 device, the device will turn on. You cannot disable the auto power on feature.
